Die casting mold factory said that die casting mold is an important process equipment in die casting production. It plays a very important role in the smooth production and casting quality. It has mutual influence and mutual restriction relationship with the production technology and operation of die casting.

Its important role is: to determine the casting shape and size tolerance grade; The filling condition of molten metal is determined by the pouring system. Heat balance control and adjustment in die casting process; The strength of the mold limits the high injection pressure; The production efficiency of die casting is affected.

Die casting mold structure:

Through the introduction of die casting mold structure, analyzed the role of each part of the mold, the basic structure form of the mold, fixed method, material selection and heat treatment have a preliminary understanding and understanding. As can be seen from the disassembly diagram of die casting mold structure, die casting mold is mainly composed of fixed mold and moving mold. The fixing die is connected with the injection part of the machine and fixed on its head plate. The moving die is installed on the middle plate of the die casting machine and closes or separates the fixed die with the movement of the middle plate.

Die casting factory says that fixed die is the main part of die casting die. The fixed die is connected with the injection part of the die casting machine and fixed in the injection part of the die casting machine and the pouring system. It is an important part of the die casting cavity. It is mainly composed of fixed mold insert, fixed mold sleeve plate, guide column, chell block, inclined guide column, pouring sleeve, fixed mold core pulling mechanism and so on. Moving die is another important part of die casting die. Moving die is another whole part of the forming part of the fixed die. It is generally fixed on the plate of the die casting machine, combined with the plate, separated from the fixed part and closed. General core-pulling mechanism and ejection mechanism in this part.

Die-casting mold factory said that the core pulling mechanism mainly includes: oblique guide column, side core, slide block, guide groove, limit block, screw, spring, nut, screw and other parts. During the die opening process, the slider is forced to move and the core is pulled out. There are two kinds of inner core pull and outer core pull, the cross section shape is mostly flat circle, to prevent the core pull slider. The components connecting the core and the inclined pin cooperate with the core pulling movement and complete the core pulling movement together with the inclined pin. In field production, it is required that the slider and the guide chute are well matched, and the pull distance cannot exceed 2/3 of the length of the guide chute. When the die is closed, the slider should be subjected to a certain pre-tightening force to prevent the metal liquid from diving into the guide chute, causing the slider to stick. After the slider is pulled out, it should be firmly kept in a certain position, so that the inclined pin can be accurately inserted into the inclined hole of the slider when the mold is closed again, so that the slider can be accurately reset. Main parameters: Total pumping distance = core pumping distance + safety value.
